Definitions
- an optical waveguide has optical scattering centers for coupling or decoupling, respectively, at the at least one site for coupling or decoupling from the outside.
- the optical waveguide contains material whose scattering can be influenced preferably by electromagnetic fields or waves or also by particles.
- this material preferably displays a low attenuation in the non-scattering condition.
- electromagnetic waves is light. Specifically with light having a higher power density, scattering centers may be created in certain materials.
- the optical waveguide must be irradiated with a light source displaying a high power density for the creation of scattering centers. Then an influence may be taken on the scattering effect produced by the scattering centers by varying the power density.
- the signal of high power ( 41 ) is coupled into the optical waveguide ( 3 ).
- the power of the signal is set here to such a high level that scattering centers are created at the site of light radiation into the optical waveguide, which centers, in their turn, couple one part of the signal into the optical waveguide in the direction of propagation in the optical waveguide.
- the middle illustration shows the preferred application in which the data signal ( 1 ) and the energy ( 8 ) for stimulating or controlling the scattering centers, respectively, are coupled from separate sources into the optical waveguide ( 3 ).
